Application filed March 1, 1926. saia- 1%.91577.

The device forming the subjectmatter of this application is a square, adapted to be used for framing, drafting and beveling, the square comprising a body and an arm, and novel means being provided for holding the arm at different angles with respect to the body; i I v Another object of the invention is so to construct the device that rafters and the likem'ay be cut by degree rather than by pitch. 7

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains. v

WVith the" above and other Objects in view which will appear as the des'cription proceeds, the invention resides in the combina tion and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings Figure 1 shows in plan, a square constructed in accordance with the invention, the square being opened for use;

Figure 2 is a detail enlarged from Fig.- ure 1;

Figure 3 is a section taken about on the line 33 of Figure 2;

Figure 4 is a tragmental plan showing the opposite side of the square from that which is delineated in Figure 1;

Figure 5 is an elevation wherein the square is viewed edgewise;

Figure 6 is a sectional plan showing a portion of the arm in relation to one of the side plates of the body of the square;

Figure 7 is a section taken about on the line 77 of Figure 6 Figure 8 is a plan showing a portion of one of the side plates of the body of the square.

The square forming the subject matter of this application preferably is made of metal throughout, and includes a body 1 and an arm 2 connected adjustably to one end of the body. The body l is made up of plates 3 and 4, a spacer 5 being secured between the plates 3 and 4, at the outer end of the body 1, so as to form a slot 6 in the body, into which the arm 2 may be folded, when it is desired to dispose the article in compact form. Adjacent to one end, the plate 3hasa beveled opening 7, in which is located a correspondingly beveled protractordisk 8, the disk 8 having a central beveled opening 9. By means of one or more securing elements 10, the protractor disk 8"is connected permanently and rigidly to the arm 2, the constru'ction being such that the arm 2 is mount ed permanently on the plate?) of the body 1 for swinging or pivotal movementwith re spect thereto. The plate 4 of the body 1 has an opening 11, and there is a tapered opening 14 in the arm 2, the opening 14 con stituting a continuation of the beveled open ing 9 in the protractor disk 8. The plates 3 and 4 and the arm 2 are united by a combined clamping andpivot member,including a bolt 12 located in the opening 11 of the plate 4, and having a flared head 15 which is received in the tapered opening 9 of the protractor disk 8 and inthe tapered opening 14 of the arm 2. A wing nut 17 is threaded on the bolt 12 and is adapted to bear against the plate 4 of the body 1. The securing elementwhich unites the protractor disk with the arm 2, projects a little way into the beveled opening 9 of the protractor disk 8, and the head 15 of the bolt 12 has a notch 16 which receives that portion of the rivet 10 that extends into the opening 9. The result is that the securing element 10 holds the bolt 12 against rotation, so that the wing nut 17 may be tightened up readily.

The arm 2 is provided on one side, and at its inner end, with seats 18, 19, 20, 21, 22 and 23, as Figure 6 will show. The side plate 4 has inwardly projecting pins 24 and 25. When the projection 24 is in the seat 21, and when the projection 25 is in the seat 19, the arm 2 will be disposed at right angles to the body 1, at one side of the body. Vhen the arm 2 is located at the opposite side of the body and at right angles to the body, the projection 24 is in the seat 18, and the projection 25 is inthe seat 22. Vhen the arm 2 is housed within the body 1, between the plates 3 and 4, the projection 24 is received in the seat 23, and the projection 25 Din uv The plate 3 ofthe body 1 has an index 26, which cooperates with the protractor disk 8, The 90 marks on the protractor disk are locatedin a line that is parallel with the longitudinal axis of the arm 2, and the necessary settings may be obtained readily, with the arm 2 either at the right or at the left of the body 1.

As shown at 27, the body is inscribed with data which will enable a carpenter and joiner to make necessary rafter settings, with dilterent bases, rise, degree to cut toot, degree to cut top, and the length of the piece being shown. In a similar manner, as shown at 28, the arm 2 may be inscribed for the convenience of the operator.

It will be understood that the Wing nut 17 may be slacked away, and then the arm 2 may be placed at any desired angle with respect to the body 1, the index 26 cooperating with the protractor disk 8 to indicate the amount that the arm has been shifted from a position at right angles to the body 1. The arm 2 is held in the position to which it has been adjusted with respect to the body 1, by tightening up the wing nut 17.

What is claimed is A square including an arm, and a body made up of side plates, the side plates be ing disposed on opposite sides of the arm, one side plate having an inwardly tapered opening, a protractor disk tapered to fit in the opening, the arm and the protractor disk having registered tapered apertures, the other side plate and the arm being provided upon their inner contacting surfaces with positively interengaging socket and projection elements by which the body and the arm may be held at adjusted angles to each other when the arm is clamped between the side plates, a securing element connecting the arm with the protractor disk, whereby the tapered protractor disk will hold the first-specified side plate and the arm to-' gether, the securing element being extended laterally into the aperture in the protractor disk, a pivot and clamping member having a tapered head received inthe aforesaid registering tapered openings and extended through the said other side plate, the periphery oi the tapered head being provided with a notch receiving the part of the securing element that projects laterally into the aperture of the protractor disk, thereby'to hold the pivot and clamping member against turning, and a nut engaging said other side plate, the nut being threaded on the pivot and clamping member and operating to clamp the side plates on the arm, and to hold the said interengaging elements interengaged.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature.
